position and offer a resistance to rattling or a play of the window sashrelative to the rider or to the frame. It is desired to mount bot-l1sashes so that they may be approximately reversed in position so as toexpose the outer side of the window pane inwardly for cleaning Theinvention resides in the particular mounting and the arrangement of thesash relative to the frame and these details will bepointed out withgreater particularity in p the specification which follows.

Referring tothe drawing herewith, Fig. 1 is a transverse section throughthe frame of a window involving my invention, the right-hand side beingon a plane, including the lower sash, and theleft-hand portion being ona plane through the upper sash. Fig. 2 is a front elevation of a windowemploying my invention. Fig. 3 is a' broken vertical section showing theprovision for mounting the sashes therein. Fig. 4is a vertical sectionthrough awindow casing showing the two sashes in closed positiontherein. Figs. 5 to .8 inclusive are diagrammatic represent-ations ofthe two window sashes shown in different operative positions toillustrate how they may be moved in the frame relative to each other.Fig. 9'is a broken front elevation of the upper sash, certain partsbeing broken away for greater clearness. F lg. is a side elevationof,theupper sash. Fig. 11 is a broken front view of the lower sash,certain parts being'broken away. 12 is a side elevation of the lowersash, and Figs. 18 and 14 areside. and frontv elevations respectivelyofgtherider upon which the lower sash is mounted. Like numerals ofreference are employed to designate likepartsin all the views. 7 i iIncarrying out my invention, 1 contemplate thatthewindow sash at the,upper part of the framewill not be adapted to slide verticallyinthejframe but will be pivoted at its lower end. The; lower sash,however, is

adapted to slide vertically in the frame and also to be pivoted at itslower end to swing inwardly into the roon The window casing s ofordinary construction, having a window Jamb 1 at the right-hand side ofthe casing and a similar jamb 1 at the opposite side. The Jamb comprisesan upright plate at each side of the window with a stop member 2 at theouter side of the frame, this stop member furnishing a support for theouter side of the upper sash 3. The lower sash 1 is mounted upon riders5 at each end. The jambs 1 and 1 are formed with channels 6 therein toreceive the riders. Sash cords 7 are secured to the riders, said cordsbeing secured to sash weights 8 in the usual manner.

The lower sash is formed for attachment to the rider 5. at both itsupper and lower ends. As shown in Fig. 11, the tnper end of the sash hasa laterally projecting pin 9 to be received within a slot 10 in theupper end of the rider. The lower end of the lower sash has a recess 11therein, said recess being tapered from the lower end upwardly to apoint approximately midway between the ends of the sash. This recess, asshown in Fig. v1.2, is of sufficient width to allow play therein of aspring 12. Said spring is a flat plate of resilientnietal secured byscrews 13 to the sash at the upper end of the recess 11. The lower endextends to a point approximately flush with the lower end of the sashand has an outwardly projecting pin 13 thereon to litwithinacorresponding recess 14 in the rider. The spring plate 12 is adapted tobe pressedresiliently outward so as to hold the pin 13 thereonresiliently within the opening 14in the rider.

The rider for the lower sash is shown in Figs. 13 and 14. It comprisesan upper member 15 and lower member 16. Said members being connectedresiliently together. The upper end is grooved on its outer faceadjacent the casing to receive the sash cord 7 and an opening extendsfrom the lower end of said groove through the body of the member 15 tobetter secure the cord in place. Screws 17 are employed to furthersecure the cord against removal from the groove. On the inner side ofthe upper member 15 is formed the groove 10 closed at its lower end andopen at the upper end to allow the pin 9 on the sash to be freed fromthe rider.

,The lower end 16 of the rider is beveled at 18 to lit the window frameand the upper end llil) has attached thereto a strap of metal 19 formedin the shape of an inverted U, the legs thereof being set within thesides of the member 16 and held in position by screws 20. The upper endof the plate 19 extends about the portion 16 and has a central openingto receive a screw 21 secured within the lower end of the upper member15. The lower end of the screw 21 is cylindrical and is slidable withinthe plate 19 for a limited distance. A spring 22 is placed about thelower shank of the screw and serves to hold the two members 15 and 16resiliently apart. It will be obvious therefore that the sash may bemounted upon the rider by connecting the lower pins 13 upon the sashwithin the'open ings 1 1 in the rider. The sash may be then pulledupwardly to bring the pin 9 within the upper end of the groove 10 and indoing so the spring 22 will be compressed to allow the shortening of therider. When the pin 9 is within the groove the tension upon the spring22 will tend to force the pins 9 and 10 apart, thus holding the pinsfirmly within the'openings in the rider and preventing play thereof.

The upper sash 3, shown in Figs. 9 and 10, has at its lower end on eachside thereof recesses 11 and springs 12 similar in all respects to thesprings upon the lower sash. Pins 13 on said springs are adapted to fitwithin openings 23 in the window jamb 1' and 1 as shown in Fig. 3.

In'operating my window, it will be possible to reverse the lower sash byraising it along with its rider to the upper end of the casing. Iprovide a narrow stop member 2 1 at the upper forward side of thechannel 6 in the casing, and against this stop the rider will engage andbe thus limited in its upward movement. If the sash is then pushedfurther upward the spring 22 upon the rider will be compressed and thepin 9 upon the sash will be lifted out of the groove 10. I provide agroove 25 in the forward side of the window jamb in front of the channel6, through which the pin 9 may be moved when the lower sash has beenraised to free the pin from the groove 10. Thus the sash may be swunginwardly at its upper end from the position shown in Fig. 5 to thatshown in Fig.- 6, thus bringing the outer face of the window paneinwardly for cleaning or otherwise. In this swinging movement the lowerpins 13 are held firmly within the recesses 1s in the riders to form apivot.

While the lower sash is in its reversed position, the upper sash may bethen moved inwardly about the pivot formed by the pins 13 into theposition shown in Fig. 7. It will be noted that the upper sash issomewhat limited in its swinging movement by the upper end of the lowersash so that the upper sash may not be entirelyreversed. The upper face,however, will be exposed in the room for cleaning.

It sometimes is desirable to have the window closed except for a vent atthe upper end and provision is made to allow the upper end of the uppersash to swing inwardly to a certain extent, as shown in Fig. 8. Thisswinging movement is accommodated by the forming of tne contact faces ofthe two sashes shown in Fig. 4. The lower end of the up per sash isbeveled forwardly to provide a face 2-6 to contact against the face 27of the lower sash. The upper portions of the adjacent sash faces arebeveled to provide a space indicated at 28 to allowa limited movementinwardly of the upper sash as indicated. This will allow a vent at theupper end without necessitating the unlocking of the sash except at theupper end, and it is understood that means may be provided, if desired,to lock the upper end of the sash in adjusted position.

The advantages of this type of window lie in the resilient and positiveconnection between the two sashes and their supports. The upper sa. h isconnetced at its lower end firmly with the casing. The lower sash issimilarly pivoted and it is held tightly in contact with the riderthrough the resilient action of the spring 22, tending to hold the pins9 and 13 away from each other and into frictional contact with therecesses in which they it In removing the sashes from their supports, itwill be necessary to compress the springs 12and 12. These springs willbe accessible for compression only when the sashes have been swunginwardly, as previously described, to such an extent as to expose thesprings after which the pins 13 or 13, as the case may be, maybe forcedinwardly toward the sashes and into the recesses 11 to allow the removalof the pin 13 and 13 in an obvious manner.

The further advantages of this construction will be apparent to thoseskilled in the art. 1 V i Having thus described my invention, what Iclaim as new and desire to protect by Letters Patent is:
